Abstract

An adaptor is provided for use with the combination of a pressure pipe down a drilled well, a rotary pump at the well bottom and a surface-located rotary drive for the pump. The adaptor is secured to the pressure pipe, and also to a housing member intended to remain stationary, and includes an axial (longitudinal) passage capable of receiving the drive string, and large enough to allow oil to pass through the passage around the drive string. The adaptor also has an open-ended transverse passage intersecting the longitudinal passage. One end of the transverse passage is closed and the other is connected to a discharge pipe extending generally radially away from the adaptor, such that the discharge pipe functions to restrain the adaptor against rotation.
